Electronic Spectra ofCyclohyphen;Octatetraene, Tetraphenylene, andshyphen;Dibenzcyclohyphen;Octatetraene

摘要

The electronic transition energies ofcyclohyphen;octatetraene, tetraphenylene andshyphen;dibenzcyclohyphen;octatetraene have been calculated by treating each molecule as four separate pgr;hyphen;electron subsystems, the excited configurations of which interact under the influence of the Hamiltonian for the complete system.The calculated transition energies forcyclohyphen;octatetraene and tetraphenylene are in good agreement with experimental data, while the calculations forshyphen;dibenzcyclohyphen;octatetraene suggest that the absorption data for this compound is in error.
